IRQ list support for enabling specific IRQs without common runtime
This adds back DECLARE_IRQ() support when building without common
runtime. With this, we can enable only a subset of IRQs and avoid
linking in other unused IRQ handlers.
Note that after this change, all boards without common runtime need to
have a ec.irqlist file.
BUG=None
TEST=Build Keyborg and check it still works.
TEST=make buildall
BRANCH=None
